.SPECIFICATION forming part of Letters Patent No. 735,320, dated August 4, 1903. Application tiled October 7, 1902. Serial No. 126.300. (No model.)

To all whom it may concern.-

Be it known that I, DAVID F. VAUGHAN, a citizen of the United States, residing at Haddonfield, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Means for Securing Splice-Bars to Rails, of which the following is a full, clear, and exact'description, reference being hadv to the accompanying drawings, of which- A Figure l is asection through a railway-rail and splice-bars, showing the bolt in place se- Fig. 2 is a splice-bars for securing the same together,

showing two of the bolts in place, being a` horizontal section as on line moc, Fig. l. Fig.

3 is an enlarged end View of the bolt.

The object of this invention is to provide a bolt adapted to be used for securing the usual splice-bars to rails, in which the screw-threaded portion of the bolt shall be of increased" 4strength without material addition" to the cost of making the bolt and which may be used in connection with the ordinary splicebars now in use.

The invention consists in upsetting the boltblank adjacent to the end thereof in the form of an oval in cross-section and providing such upset portion with screw-threads adapted to' receive theusual nut.

Referring to the accompanying drawings, 1 designates the body of the bolt, which is round in cross-section; l, the head5'lb, the part adjacent to the latter, which is oval in cross-section, and l? is the screw-threaded end of the bolt. When in use, the bolt is passed through oval holes 2 inthe splice-bars 3 on opposite sides of the rail 4 and through a hole 5 in the web of the rail, anda nut 6 is screwed onto the bolt `against an interposed washer 7. r

`The foregoing describes generally the construction now in common use on railways.

` construction of the usual bolt, except that I upset the end portion in the form'of an oval in cross-section, the longest or horizontal diameter of which oval is greater than that of the body of the bolt and the shortest or vertical diameter of the oval is slightly greater the bolt oval in cross-section the oval part 1b, adjacent to the head, maybe dispensed with and that part be made of the same form and thickness as the body of the bolt the oval end portion of the bolt extending through a suitable oval hole in the splice-bars sufcing to prevent the turning of the bolt when the nut is screwed up or unscrewed.

Having` thus described Y my invention, I

claim as new and desire to secure by Letters `lEatent- Afl. A' bolt for securing splice-bars to rails `having the, enlarged screw-threaded end portion oval in cross-section, substantially as and `for the purpose recited.

2. The combination of the rails, having the holes, the splice-bars having the oval holes, andthe bolts having respectively the screwthreaded end portions oval in cross-section, and the nuts on said bolts for clamping said parts together, substantially as and for the purpose recited.

In testimony whereof I have hereunto affixed my signature this 23d day otJuly, AuD.

DAVID E. VAUGHAN.
